デバイスごとのパッケージ図は、PDF版データシートをご参照ください。
The TPS61256A integrates a power-save mode to improve efficiency at light load. In power save mode the converter only operates when the output voltage trips below a set threshold voltage.
It ramps up the output voltage with several pulses and goes into power save mode once the output voltage exceeds the set threshold voltage.
The PFM mode is left and PWM mode entered in case the output current can not longer be supported in PFM mode.
